Regular expression to find URLs within a string
Solution 1:
This is the one I use
(http|ftp|https):\/\/([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])
Works for me, should work for you too.
Solution 2:
Guess no regex is perfect for this use. I found a pretty solid one here
/(?:(?:https?|ftp|file):\/\/|www\.|ftp\.)(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[-A-Z0-9+&@#\/%=~_|$?!:,.])*(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[A-Z0-9+&@#\/%=~_|$])/igm
Some differences / advantages compared to the other ones posted here:
- It does not match email addresses
- It does match localhost:12345
- It won't detect something like
moo.com
withouthttp
orwww
See here for examples
Solution 3:
text = """The link of this question: https://stackoverflow.com/questions/6038061/regular-expression-to-find-urls-within-a-string
Also there are some urls: www.google.com, facebook.com, http://test.com/method?param=wasd, http://test.com/method?param=wasd¶ms2=kjhdkjshd
The code below catches all urls in text and returns urls in list."""
urls = re.findall('(?:(?:https?|ftp):\/\/)?[\w/\-?=%.]+\.[\w/\-&?=%.]+', text)
print(urls)
Output:
[
'https://stackoverflow.com/questions/6038061/regular-expression-to-find-urls-within-a-string',
'www.google.com',
'facebook.com',
'http://test.com/method?param=wasd',
'http://test.com/method?param=wasd¶ms2=kjhdkjshd'
